CARDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 708,046, dated September 2, 1902. Application filed March 28, 1902. Serial No.100,434. (No model.)

To CI/ZZ whom, it may concern: Be it known that we, WILLIAM HENRY HOYLE, cotton-spinner, residing at 86 Chorley New Road, and THOMAS BARKER, consulting engineer, residing at 164 Cook street, Bolton, in the county of Lancaster, England, subjects of the King of Great Britain and Ireland, have invented certain new and useful Improvements in Oarding-Machines, of which the following is a specification.

Our invention relates to machinery for the production of that class of yarn known as condenser-yarn.

Hitherto the method used for producing condenser-yarn has been to feed the material into a carding-engine in one broad fleece the full width, or nearly so, of the wire clothing on the cylinder and divide the material as it is delivered into the required number of ends or slivers, then pass them on'through rubbers to rub the ends into round yarn.

The main feature of our invention is to divide the material at the feed into sections, and in order to gain the advantage of doubling each section may be composed of two or more ends. -In other words, we divide the material before it enters the machine in place of dividing it as it is being delivered from the machine, so that the condenser-yarn or the like is fed to the machine in separate and distinct in passing therethrough, and we thereby recondense condenser yarn or it might be sliver or other fiber. Under our invention each section is drawn out or elongated to the required fineness, which fineness is regulated by the relative speed of the doffer and feed roller or rollers.

Our improvements will be clearly understood from a perusal of the following specification, which when read in conjunction with the accompanying drawings will enable any person skilled in the art to which it appertains to thoroughly-grasp the invention.

In the said drawings, on Sheet 1 Figure 1 represents a general elevation of our improved machine for recondensing condenser-yarn or the like and is inserted merely to show the framing and general driving parts, so as to fully illustrate the invention. On Sheet 2 Fig. 2 is a sectional end elevation of the complete machine, the framing and driving parts feed-plate.

being omitted for the sake of clearness. On Sheet 3 Fig. 3 is a plan view of part of the main feed-plate, which is formed with sectional compartments. The figure shows two of the section guide plates or blocks in position in one of the compartments of the main Fig. 4 is a sectional elevation of the main feed-plate, &c-., indicated in plan in Fig. 3. Fig. 5 shows a sectional end elevation of a modified arrangement of using top section-rollers in lieu of the section guide plates or blocks. Fig. 6 is a plan view of such modified arrangement. Fig. 7 shows a section of a further-modified arrangement, in which section plates or blocks acted on by levers and weights are used. Fig. 8 is a plan view of the arrangement indicated in Fig. 7.

In carrying our invention into effect under our improved method we arrange to feed the material to be acted upon through the machine in separate and distinct sectionsthat is to say, we wind ordinary condenser-yarn aor the like in sections or otherwise upon bobbins b b. The bobbins containing the condenser-yarn a to be recondensedare acted upon by rollers c c, the function of which is to unwind the condenser-yarn from the said bobbinsb b by frictional contact therewith. This yarn next passes over a rod or bar d to the feed-roller e, which is mounted below the main feed-plate f, the said plate f being carried by pedestals, which support the feed-roller. This main feed-plate f is formed with compartments f, designed to receive loose section plates or blocks f which fit loosely in the said compartmentsf' and rest upon the material passing over the feed-roller e. The loose sectionplates f are formed with guide-grooves f f the main feed-plate being also formed with grooves f, the said grooves serving to guide, consolidate, and keep separate the sections of condenser-yarn passing through the machine. The condenser-yarn leaving the main feed-plate is acted upon by the revolving cylinder g, which is covered with card-wire g, the cylinder being of comparatively small diameter and having a fancy-rollerh combined therewith. From the main cylinder the material is acted upon by the dofier i, covered with card-wire i, and from which it is stripped by the doffing-combj. As the material is fed through the machine it is elon- ICO- gated and drawn out in separate and distinct sections, so as to produce the requisite fineness, the degree of severity of the elongation being regulated by the relative speed of the doffer and feed roller or rollers. Leaving the dotfer z', the stripped material in separate and distinct sections now passes to the usual or ordinary rubbers 7t 7a, which rub the sections of material into round or condenser yarn a without twist. These rubbers k k are preferably driven at a comparatively high speed. We have found a speed of about one thousand per minute to be suitable. From the rubbers 7t 7c the fine condenser-yarn 0, passes to one or more taking-up bobbins Z Z, the yarn being wound on by frictional contact of rollers m m. In Fig. 2 we have indicated a wellknown form of traverse-bar 0 and yarn-guide o for winding the yarn in section upon the bobbins Z Z. This winding on or spooling of the yarn may obviously be varied.

In Figs. 5 and 6 a slightly-difierent form of sectional feed is indicated. Under this modified form 6 is the feed-roller, which is preferably in one continuous length from end to end of the machine, while f is the main feedplate, having journals f formed therein. Upon the feed-roller e rest short top rollers 1', formed with trunnions r to engage the journals f, the said short rollers resting on two sections of material in the form shown in the drawings and being weighted by weights r suspended on hooks T The main cylinder is lettered g, as before. Trumpet-mouthed guides s of any suitable description may guide the material in sections into and between the feed-rollers.

In the modification shown in Figs. 7and 8 the main feed-plate f is arranged above the feedroller 9. This main feed-platef supports the section-feed plates or blocks f which are formed with grooves or recesses f f while the main feed-plate f is formed with recesses f These section-feed plates or blocks rest upon the material on the feed-roller e, as before described. To weight the plates or blocks f we employ levers 25, which rest in a recess t, formed in the middle of each section plate or block f the said levers being weighted by adjustable weights, as at 15 To hold the levers t firmly, they may be hooked into the main feed-plate f", as indicated at i Fig. 7.

It will be understood that under our invention we prefer to dispense with the use of clearers and traveling flats in connection with the main cylinder g.

The operation of our improved arrangement is as follows: The material a, which may be ordinary condenser-yarn or the like, is first wound on the bobbin or bobbins in sections side by side to each other. These bobbins are then placed upon the rollers, which revolve in the direction of the arrows, and so unwind the material, which then passes through the section guide-grooves in separate and distinct sections and (by the action of the feed roller or rollers) is fed into the machine to be elongated or drawn out to the required fineness by the carding and elongating mechanism. As the material is being fed into the machine the wires on the cylinder detach the material (fiber by fiber) from the feed, and in doing so the fibers of each section are drawn in between the wires on the cylinder, thus keeping the sections of material separate and distinct from each other. The fancy-roller raises the material slightly above the points of the Wires on the cylinder. The doifer then takes the material from the cylinder. The material is then stripped oif the dofier by the doffing-comb. The sections of material then pass in between the rubbers to be rolled or rubbed into round yarn without twist. The yarn is then wound on bobbins for further operation.

It is obvious that our method of elongating or drawing the material to the required fineness (as it is passing through the machine in sections) is of great advantage in producing fine condenser-yarn.

We declare that what we desire to secure by Letters Patent is- 1. In an apparatus for the purpose described,the combination with the carding-cylinder, of an elongated feed-roller in proximity thereto,and a plurality of independently-movable section-feed devices arranged in juxtaposition to said feed-roller, substantially as described.

2. In combination, in an apparatus for recondensing condenser-yarn or the like, the combination with the plurality of bobbins, of a feed-roller, a plurality of section-feed devices in juxtaposition to said roller, a main cylinder g, a doifer i, and doffing-combj, and a fancy-roller h and rubbers 70, k, for rubbing the sections of yarn, substantially as described.

3. In combination in an apparatus such as is herein described a plurality of bobbins for holding condenser-yarn, means for withdrawing such yarn, a sectional feed, comprising an elongated roller, aplurality of independentlymovable presser devices cooperating therewith, a main cardingcylinder a doifer and doffing-comb, rubbers for rubbing the yarn and means for batching the recondensed yarn substantially as described.

4. In a machine of the class described, the combination with the carding-cylinder g, of a single elongated feed-roller e in proximity thereto,a feed-plate above the feed-roller having a plurality of compartments, and a plurality of blocks seated in said compartments and having guiding-grooves in their lower portions, substantially as described.

In witness whereof we have hereunto set our hands in presence of two witnesses.
